That is pretty old stuff...

There are better ways to do that in CMake now:

cmake --help-command add_custom_command
....

        Arguments to COMMAND may use "generator expressions" with the syntax
        "$<...>".  Generator expressions are evaluted during build system
        generation to produce information specific to each build
        configuration.  Valid expressions are:

          $<CONFIGURATION>          = configuration name
          $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
          $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
          $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

This should work:
   COMMAND $<TARGET_FILE:FilterWidgetCodeGen>
